When it comes to creating custom types of assemblies or holding material together in a secure, tight and reliable fashion in construction and manufacturing, fully threaded studs are often the fastener of choice.
The name really describes these fasteners in a clear and concise way. They are also called all thread studs or more simply all thread or threaded rod. There are many different options for this type of fastener from different alloys, different threads and standard and custom lengths.
Working with All Thread
Working with fully threaded studs is really very easy, which is why these are used in fabrication and construction in a range of different applications. The threaded stud is simply inserted into a pre-drilled hole in either metal, wood or combinations of different materials. The two ends of the stud are then threaded with the correct sized nuts and tightened, providing a very secure hold.
It is also possible to use threaded handles, spindles or knobs to create a grip on a component or part. As they can be easily removed using the same process, this is an ideal option for anything that has to be assembled and taken apart multiple times.
When the all-thread needs to stay secure, it is possible to use a thread-locking adhesive before applying the nut, handle or knob. This will secure the attachment in place for a more permanent grip that will not need to be tightened to maintain the firm hold required.
Cutting Threaded Rod
Ideally, purchase fully threaded studs pre-cut to the specific lengths required. As these studs are threaded the entire length, cutting will pose a problem with threading the nut on the cut edge. This is only true if the rod is cut using a standard saw.
A better option is to actually grind the threaded rod and turn it as it is ground in a chamfered or sloped side. This allows the nut to slip over the sloped end and then start treading where the threads have not been touched. This saves having to work on the edges to get the nut to thread.
Another option when cutting all-thread is to thread a nut so the top of the nut is at the point of the cut. Cut the all thread and then just remove the nut, it will re-work the very edge of the last thread and allow easy threading with the next application of the nut.
